Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669420, here are decompositions:

3 + 8669417 = 8669420
31 + 8669389 = 8669420
79 + 8669341 = 8669420
103 + 8669317 = 8669420
127 + 8669293 = 8669420
181 + 8669239 = 8669420
241 + 8669179 = 8669420
307 + 8669113 = 8669420

Showing the first eight; more decompositions exist.
